If so, how? • What is the strongest bone(s) in the human body? • Which is stronger: your bones or steel? • What does the word “skeleton” mean? • Are teeth considered bones? • What is the largest bone in the human body? • Are your bones alive?

  2. The Skeletal System:What do I need to know? • The five functions • Major components of bones – pg 479 • Major bones of the human body – pg 475

  3. At your table… • As a group, brainstorm the five functions of the skeletal system. • REMEMBER: I already gave you two!

  4. - The Skeletal System Functions of the Skeletal System • Your skeleton has five major functions: • provides shape and support • enables you to move • protects your organs • produces blood cells • stores minerals and other materials until your body needs them.

  5. - The Skeletal System Cross Section of a Bone Compact Bone Periosteum Spongy Bone Bone Marrow

  6. Major Components of Bone • Periosteum – thin, tough membrane that covers all of the bone except for the ends – blood vessels and nerves enter here • Compact Bone – hard, dense bone tissue that is located just under the periosteum • Spongy Bone – layer of bone tissue having many small spaces – inside the layer of compact bone • Bone Marrow – soft connective tissue that fills the internal spaces of bones • Cartilage – protective tissue that covers the ends of bone- page 477

  7. Major Bones of the Human Body • Though there are 206 bones in an adult’s body, we will learn the names of only 20.
